Definitions

  • the present invention relates to a device for adjusting a flow of air flowing in a ventilation duct.
  • This device finds particular application for the equipment of a mechanical ventilation system (VMC) or air conditioning of a room.
  • VMC mechanical ventilation system
  • FIG. figure 1 A device 1 for adjusting a flow rate of air flowing in a ventilation duct, known from the state of the art, is represented in FIG. figure 1 .
  • This device 1 comprises a tubular body 2 designed to be engaged entirely within the air duct.
  • the device 1 comprises a seal 4 mounted on the body 2 to seal between the body 2 and the air duct.
  • the device 1 comprises flaps 6 provided to occupy a plurality of positions within the body 2 corresponding to a plurality of air passage sections.
  • the body 2 comprises grooves 8 and the flaps 6 comprise ribs of complementary shapes arranged to slide in said grooves 8.
  • the device 1 finally comprises a flexible chamber 10 adapted to inflate or deflate according to the pressure difference between upstream and downstream end portions of the body 2.
  • the invention aims to remedy this drawback.
  • each flap is provided with the male drive means, and the ring is provided with the female drive means.
  • axis transverse to the axis of the body an axis belonging to a plane transverse to the axis of the body.
  • the installer When an installer wishes to preset or adjust the air flow flowing in an air duct equipped with the device according to the invention, the installer simply drives the ring in rotation relative to the body.
  • the male and female drive means cooperate and move each flap inside the body so as to reduce or increase the air passage section.
  • each flap extends at an upstream end portion of the body, in the air flow direction, and the male and female drive means are arranged at the a downstream end portion.
  • the male drive means comprises a finger
  • the female drive means comprises a tab extending in a plane transverse to the axis of the body and through which is formed a C-shaped light adapted to receive the finger .
  • Such an arrangement makes it possible to convert the pivoting of the ring relative to the body about the axis of this body into a pivoting of the flap inside the body around its pivot axis.
  • the light has two end portions shaped to receive and immobilize the finger.
  • each flap is molded with the body, and each flap has a thinning material defining the pivot axis of the flap.
  • each shutter and the body is carried out jointly by molding.
  • the number of elements constituting the device is limited and the assembly method of the device is facilitated.
  • the body is provided with a male detent member and the ring is provided with a female detent member, or vice versa, the male and female detent members being adapted to prohibit the axial translation of the detent. ring on the body, and allow the ring to pivot on the body.
  • the ring has a fluted outer face.
  • the ring has an outer diameter substantially equal to the outer diameter of the body, and preferably an inner diameter substantially equal to the inner diameter of the body.
  • the device can then be engaged in its entirety inside an air duct whose inner diameter is substantially equal to the outer diameter of the body and the ring.
  • the device comprises a flexible chamber arranged to inflate or deflate, as a function of the pressure difference between the upstream and downstream end portions of the body.
  • Such a flexible chamber makes it possible to regulate the flow rate of air flowing in the air duct around a setpoint value, whatever the airflow disturbances to which the duct is subjected.
  • the device 20 comprises a tubular body 22 extending along an axis 24.
  • the body 22 is intended to be fluidly connected to said air duct.
  • the body 22 is for example engaged in part or entirely in the air duct.
  • the body 22 has an upstream end portion 22a and a downstream end portion 22b.
  • the body 22 is provided with a male detent member 26 (shown in FIGS. figures 3 and 9 ) provided on the downstream end portion 22b.
  • the male detent member 26 here takes the form of an annular projection.
  • the shutters 28 are molded with the body 22 and have material thinning (shown in FIG. figure 9 ) defining the axes 30. These axes 30 extend at the upstream end portion 22a of the body 22 and are transverse to the axis 24.
  • the flaps 28 are provided with fingers 32 forming male drive means.
  • the fingers 32 are arranged at the level of the downstream end portion 22b.
  • the device 20 comprises a ring 34 pivotally mounted on the downstream end portion 22b of the body 22 about the axis 24.
  • the ring 34 has an outer diameter substantially equal to the outer diameter of the body 22 and an inner diameter substantially equal to the inner diameter of the body 22.
  • the ring 34 has a fluted outer face
  • the ring 34 is provided with tabs 36 in which are formed C-shaped openings 38 forming female drive means.
  • the tabs 36 extend at the level of the downstream end portion 22a, in a plane transverse to the axis 24.
  • the lights 38 are adapted to receive the fingers 32. More specifically, the lights 38 have a width slightly greater than the width of the fingers 32. Thus, the sliding of the fingers 32 in the slots 38, when the flaps 28 pivot about the pins 30 , is made possible.
  • the lights 38 have two end portions 38a and 38b (shown in FIGS. Figures 4 to 6 ) shaped to accommodate and immobilize the fingers 32.
  • the ring 34 is provided with a female detent 40 (shown in FIG. figure 9 ).
  • the female latching member 40 here takes the form of an annular groove.
  • the male and female ratching members 40 are designed to prevent the axial translation of the ring 34 on the body 22, and to allow the ring 34 to pivot on the body 22.
  • the device 20 finally comprises a regulating member 42 adapted to regulate the flow of air flowing in the body 22 around a set value.
  • the regulator 42 (shown in FIG. figure 11 ) comprises a flexible chamber 44 arranged to inflate, or to deflate, depending on the pressure difference between the upstream end portion 22a and the downstream portion 22b of the body 22.
  • the flexible chamber 44 is mounted on a base 46.
  • the regulating member 42 comprises a support 48 on which is fixed a reinforcement 50 engaged inside the flexible chamber 44.
  • the regulator member 42 finally comprises a cover 52 having an opening 54 inside which the flexible chamber 44 is engaged.
  • the cover 52 and the support 48 enclose the base 46.
  • the cover 52, the support 48 and the base 46 are engaged in a housing 54 (shown in FIG. figure 10 ) formed inside the body 22, so that the flexible chamber 44 extends radially inside the body 22 between the flaps 28.
  • the ring 34 is mounted on the body 22 (as shown in FIG. figure 4 ).
  • the fingers 32 are received and immobilized by the end portions 38a of the slots 38.
  • the flaps 28 are in the separated position.
  • the fingers 32 are then released by the end portions 38a and slide inside the slots 38 until they are received and immobilized by the end portions 38b.
  • the flaps 28 pivot about the axes 30 so as to successively occupy their intermediate position (represented in FIG. figure 5 ) then their close position (represented in figure 6 ).
  • the installer When the installer wishes to increase the air passage section, and consequently the flow of air flowing in the air duct, it causes the ring 34 to rotate about the axis 24 in a direction opposite S2 in the sense S1.
  • the fingers 32 are then released by the end portions 38b and slide inside the lumens 38 until they are received and immobilized by the end portions 38b.
  • the flaps 28 pivot about the axes 30 so as to successively occupy their intermediate position (represented in FIG. figure 5 ) then their close position (represented in figure 6 ).
  • the invention is not limited to the sole embodiment of the device described above by way of example, it encompasses all the variants.
  • the ring may be provided with a male drive member and each flap may be provided with a female drive member.
  • These male and female drive means are arranged such that in response to a pivoting of the ring on the body, the male drive means cooperates with the female drive means to change the position of each flap, and as a result the air passage section.
  • the ring and the body have complementary indexing means adapted to receive and immobilize the ring in three predetermined positions relative to the body, corresponding to the spaced apart, intermediate and close positions of the flaps.
  • the indexing means comprise a plurality of notches formed on an inner face of the ring. These notches are arranged to cooperate with at least one boss formed on the body.
